Since the start of modern mechanical engineering, numerous patents, new developments and innovative details can be attributed to the inventive spirit of INDEX. Perhaps that is the reason why we are always looking to push our limits and be better. Our ultimate goal is to build the best turning machines through top performance. Check out the current INDEX & TRAUB product portfolio including production turning machines, turn-mill centers, turn-grind centers, vertical turning machines and CNC multi-spindle turning machines.

INDEX & TRAUB automatic turning machines are especially designed for fast, cost-effective production of standard automated turned parts and complex CNC turned parts. The flexibility of CNC technology, combined with the high speed of classic automation, allows the production of small to medium lot sizes at competitive prices.

The INDEX & TRAUB universal turning machine has an excellent reputation around the world when it comes to the machining of large chuck, shaft, and bar workpieces. Through precision, efficiency, short cycle times, and ease of use, these universal turning machines have set a standard in their class. The machines can be tailored to suit any specific requirements – prototype production, small and medium series production, or for use in a production line.

INDEX multi spindle automatic lathes combine the advantages of CNC technology with those of cam-controlled machines. They can be used not only for series production of a wide range of precision parts but also for small series due to their extremely short setup times. Whatever the application, these multi spindle turning machines impress with their high performance.

INDEX & TRAUB turn-mill centers set the standard for economic, high-precision solutions tailored to the customer's needs. Standards ranging from the classic production turning machine to tailor-made machining cells equipped with handling units. For the machining of simple to highly complex parts, in small to large lot sizes, INDEX consistently offers economically and technologically superior solutions.

CNC sliding headstock automatics from INDEX & TRAUB are designed for exact and productive manufacturing of long and slim parts with a maximum diameter of 32 mm. The multitude of variants, miniturization and precision of the work pieces are but a few of the demands on a CNC swiss turning center. The TNL-series is characterized through high performance in combination with easy setup and programming.

INDEX vertical turning centers meet all requirements of a low-cost flexible series production of chuck parts. The vertical mobile motor spindle carries out the “handling” and “machining” functions. Short travel distances, combined with high rapid traverse speeds, substantially reduce time. Even high-precise grinding operations are possible on these vertical turning machines.

The turn-grind centers combine the advantages of the turning and grinding process, such as shorter cycle times, high quality and maximum process safety. In addition, the machines benefit from the rigidity of the machine concept, which is traditionally designed for the high process forces during turning and milling and ensures tolerances down to the nearest µ.

Machines previously demonstrated at trade shows or in our showroom provide all of the benefits of the world’s best turning centers, but at a reduced investment level. Each of these machines has been fully certified and has a low level of operating hours in a non-production environment.

Our used machines are modernized by our qualified employees and their decades of experience in mechanical engineering. Components are usually completely dismantled, cleaned, and repainted as required. The interior gets a “makeover” treatment. Wear parts, guide elements, fluid lines, sensors and cables in the machine area are replaced, working and milling spindles are overhauled in proven manufacturer quality, and the control system is upgraded to the state of the art.

Always well loaded. The bar loading magazines are ideally adjusted to the INDEX & TRAUB CNC turning machines for single-spindle and multi-spindle turning operations. They convince with short set-up times , fast bar change and a backlash-free guidance of the bar for high surface qualities.

Excellent software solutions for INDEX & TRAUB machine tools. Discover the new operating system iXpanel i4.0 ready for a direct communication with your business organization and the machine control. Take advantage of our outstanding programming and 3D-simulation software VirtualLine.

Virtual Machine is a software solution that supports almost all of the functionality of your INDEX machine tool and adds even further components. You simulate the exact machining, regardless of whether you carry out programming on the machine or with a CAM system. It is based on the original data of the Siemens software, the INDEX control and the machine geometry.

VirtualPro is an innovative programming aid for INDEX turning machines. A large number of powerful input masks, parameterizable sequences and geometric functions simplify programming considerably. You create the desired workpiece program more quickly and conveniently and, thus, in a more reliable manner.

Standard functions and interfaces available in the control enable easy integration of the machine in the respective production environment. You have quick access to production information and custom applications that are displayed directly on the control screen.

WinFlexIPS Plus is the enhanced version of the proven system WinFlexIPS, tailored to the ideal use of the TRAUB machines with the functionalities programming and simulation on the basis of the TRAUB TX8i CNC core – supplemented by the additional advantage of manual operation of the entire machine functionality.

The new TRAUB TNL20 - a very high-performance automatic turning machine

Productive sliding and fixed headstock turning of medium and high complexity workpieces from bar stock or with an integrated robot cell

Machine highlights TNL20

Your benefits

Simultaneous machining with 2, 3 or 4 tools

High tool pool for set-up-friendly production

Short tool changing times by means of CNC indexing axis in the tool turrets and in the front working attachment

Generous and process-reliable work area

Intelligent automation through the integrated robot cell iXcenter

Machine concept

The machine concept of the TNL20 has been systematically matched to the daily requirements of the user. So the kinematics of the machine allows effective and simultaneous machining with two or three tools.The generous and vertically arranged work area provides for the necessary degrees of freedom, as well as for very high process reliability.

The machine's crucial productivity advantage is the result of its extraordinarily high dynamics. The newly developed machine bed from gray cast iron forms the basis for utmost vibration dampening properties. And the high rigidity and thermal stability ensure optimum workpiece quality.

TNL20 in focus

TNL20-9

Simultaneous and precise manufacturing with up to three tools.

TNL20-9B

Version with the additional B-axis for highly complex parts.

Robot cell iXcenter

Intelligent automation - even more flexibility and efficiency

With the optional robotic cell, blanks and/or finished parts can be supplied and discharged quickly, safely and flexibly. The robot cell is integrated ergonomically into the machine. It can be moved easily to the left during the setup process, allowing unobstructed access to the work area of the machine. During production, the robot cell is fixed in front of the machine's work area. The robot then accesses the work area via the sliding guard of the machine, which opens automatically behind the robot cell.

Space-saving handling of blanks and finished parts

Space-saving vertical storage with up to 14 pallets stacked up

Pallets with blanks are loaded at the top, pallets with finished parts are removed at the bottom

The pallet is pulled out by the robot

The pallet storage cycles down in steps of 25.4 mm

Easy macro-programming

Using more potentials

The space above the vertical storage can be used easily for subsequent processes such as cleaning, measuring, deburring, etc.

The preparation for incorporating a fully automatic 3D measuring cell is already provided as standard
